This invention relates to furniture and more particularly to a cotintended to beused by invalids who are confined to a bed or can only be temporarily removed from abed and placed in a wheelchair.

One object of the invention is to provide a cot which may rest flat upon abed beneath a patient and may be lifted from the bed by suitable hoisting mechanism so that sheets '10 may be conveniently changed without causing pain to the patient or the patient temporarily lifted from the bed in order to afford relief from constant lying upon a mattress withresulting danger of bed sores being formed.

Another object of the invention is to permit the cot tobe folded into a chair. formation so that when lifted from the bed the patient may assume a seatedposition and thereby be '20 easily lowered into a rolling chair or, if desired, remain in the cot which will be suspended in the chair formation from an overhead support. I r

Another object of the invention is to provide a seat board whichmay be placed beneath an intermediate portion of the cot and engaged with the hoisting mechanism so that the patient will be well supported when lifted in a seated position, V 1

Another object of the invention is to provide an improved foot rest which is well supported and upon which the feet of the patient will rest while seated. v

The invention isillustrated in the accompanying drawings, wherein I Figure 1 is a perspective view showing the invalids cot in operation relative to a bed;

Fig. 2Iis a top plan View. of the cot;

Fig. 3 is a vertical sectional View showing the cot suspended ina chair forming position; I

Fig. 4 is a perspective view of the seat board;

Fig. 5 is a perspective view of the foot board, and

Fig. 6 is a perspective view showing the manner of hingedly connecting sections forming a side bar of the cot frame.

The improved invalids cot includes afab- .i5Q rio sheet 1 formed of canvas or any other strong fabric desired and along its sides and upper and lower ends is formed with pockets to receive the side bars 2 and. end bars 3 of a frame. The side and end bars of the frame may be formed of wood or metal and are releasably secured together by bolts 4: having winged nuts so that they may be easily released and the side and end bars slid out of thepockets when it is necessary to substitute a new sheet or body 1 and laundry the one previously in use. An opening 5 is formed in the sheet intermediate its length and width and this opening is bordered by circular reinforcing strips 6 which protect the margins of the opening and prevent them from fraying out and also prevent danger of the sheet tearing at the opening. By referring to Fig. 3, it will be seen that the lower end portion of the sheet or fabric body is folded back upon itself and secured to form not only a lower pocket to receive the lower cross bar 3 but also a pocket 7 which may extend outwardly and receive a foot board 8.

The side bars 2 of the frame each consists of an intermediate section 9 and upper andlower end sections 10 and 11, which are hingedly connected, as shown at 12, so that the upper section of the frame may be swung upwardly and the lower section downwardly and thereby cause the cot to assume a forma tion resembling a chair when so desired and support the patient in a seated position. Eyes 13 are carried by the end sections adj acent their inner ends and project upwardly through openings formed in the side pockets of the fabric body. These eyes extend transversely of the body and are intended to receive rods 14. ,which are of greater length than theintermediate portion and when in place serve to prevent the upper and lower sections from folding and assuming a chair forming position when the cot is lifted. The rods are preferably formed'of metal so that they will have suflicientstrength to prevent themfrom being bent or broken when in use and each carries a set screw 15 which, when tightened, will bear against the intermediate section of a side bar and apply pressure which will prevent the rod from slipping out of'the eyes into which it fits. I have also provided a seat board 16 which may be formed of wood and in dimensions approximately corresponds to the intermediate section of the cot. This seat board is intended to be placed beneath the cot, as shown in Fig. 3, and carries snap hooks 17 which are intended to pass'upwardly through the cot, as shown in Fig. 3, when the seat board is in use.

In order to lift the invalids cot, I employ hoisting mechanism includinga pulley wheel 18 which is rotatably carried by a hanger 19 adapted to be suspended from an overhead support above the bed. In the present illustration, the hanger is suspended from a tripod including a bar 20 to which the hanger is attached and supporting legs 21 which con verge upwardly and are connected with the ends of the bar 20 by couplings 22. The bar 20 extends longitudinally of the bed, and from an inspection of Fig. 1 it will be readily seen that when the cot is lifted the bed may be easily slid transversely frombeneath the tripod. It will be obvious that, if desired the hanger 19 could be engaged with an eye bolt screwed into a ceiling beam disposed above the bed or with any other suitable sup port strong enough to carry the weight of the cot and a patient resting thereon. Chains 23 are passed about the pulley and each chainhas one end engaged with a ring 24 from which extend chains 25 and 26, the lower ends of which are to have selected links engagedwith the hooks 27. The other ends of thechains 23 carry hooks 28 which may be engaged in the rings 24 or selected links of the chains 23. It will thus be seen that by pulling upon the chains 23 to draw them over the pulley the cot may be lifted fromthe bed and by engaging the hooks 28 in the rings 24 or links of the chains 23 the cot may be suspended at a desired height. Sheets may then be very easil changed and the patient then again lowered upon the bed or the patient may be allowed to remain suspended upon the cot inorder to allow the bed to be aired and also to relieve the patient from continually lying upon a bed'with the resulting danger of bed sores being formed. 7

When it is desired to place the patient in a rolling chair which may be of a conventional construction or may merely consist of an ordinary dining room chair having casters ap plied to the lower ends of its legs, the cot is first elevated with therods 14 in place and the seat board 16 placed beneath the intermediate. section of the cot. The cot is then again lowered until it rest upon the seat board and the hooks 17 thereof project upwardly thror'igh the cot. The rods are then removed and the rings 29 carried by the straps or small chains 30 which are suspended from the rings 24. are engaged with the hooks 17. The foot board 8 is passed through the pocket 7 which is to extend outwardly from v the cot, as shown in Fig. 3, and the hooks 31 at the ends of the bracing straps 31 carried by the foot board are engaged with the eyes 13 carried by the lower sections 11 of the side bars. After the seat board and the foot board are in place, the chains 23 are again drawn upon to lift the cot and as the cot is elevated the bed may be slid transversely from beneat-h the cot. The pull upon the chains 26 will cause the upper end portion of the cot to be swung upwardly and form the back of, a chair and the lower end portion of the co'twill swing downwardly so that the patients feet may rest upon the foot board. It will thus be seen that the patient will bcususpended in a seated position and may then be easily lowered onto a wheel chair @1- if so desired the patient may remain seated in the cot While itis suspended from the overhead support. The cot may, therefore, be employed to lift the patient-in a reclining position or it may support the patient in a seated position. Since the links of the chains 25 and 26 ares lectively engaged with the hooks 27, the incline of the back and leg, supporting portion of the chair may be con trolled. 0, 1
